Which description matches frostnip?

Which description matches frostnip?

• A. Frostnip involves superficial freezing with numbness and no tissue necrosis
• B. Frostbite involves actual freezing of tissue with ice crystals
• C. Frostbite only affects superficial epidermis
• D. Frostnip causes necrosis

Answer: (A)

Frostnip is a mild, superficial cold injury where freezing affects only the outer skin, producing numbness and pale skin but no tissue death. Because there’s no deeper cell damage, there is no necrosis and symptoms resolve with warming. This is why the statement describing frostnip as superficial freezing with numbness and no tissue necrosis is the best fit. The other statements describe frostbite, which involves actual freezing with tissue injury that can include ice crystal formation and necrosis, can extend beyond the epidermis, and does not fit frostnip.
